Key Lime Pie has a tangy, creamy filling made from fresh key lime juice and sweetened condensed milk, set in a buttery graham cracker crust. It chills in the refrigerator until firm, making it a great make-ahead dessert that's ready in roughly 3 hours total, including bake and chill time.
Prepare the crust by mixing graham cracker crumbs, sugar, and melted butter in a mixing bowl. Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan.
Bake the crust for 10 minutes until set. Remove and let it cool slightly.
Whisk Together: Lime juice, lime zest, sweetened condensed milk, and egg yolks in a separate bowl until smooth and creamy.
Pour the filling into the cooled crust, spreading evenly.
Bake the pie for 15 minutes at 350°F (175°C) until the filling is set but still slightly jiggly in the center. Let it cool to room temperature, then refrigerate for at least 2 hours before serving.
